Introduction: Sleep quality has become a public health concern due to serious impacts on individual’s health outcomes. Thus, this cross-sectional study aimed to determine the sleep quality and its associated factors among adults living in the province of Terengganu, Malaysia. Materials and Methods: Socio-demographic information was self-reported whilst anthropometric measurements were measured by trained researchers. Sleep quality was assessed using the validated Pittsburgh Sleep Quality Index (PSQI) whilst eating behavior was measured using the Dutch Eating Behavior Questionnaire (DEBQ). Descriptive statistics and multivariable linear regression models were employed using IBM SPSS version 25.0. Results: A total of 580 participants were enrolled (mean age = 29.1 ± 10.0 years; 51.2% female), of which 74.7% (n = 433) had poor sleep quality (PSQI global score > 5) with a total sleep duration per night of 6.2 ± 1.6 hours. Gender (p-value=0.044), educational level (p-value=0.001), emotional level (p-value=0.005) and external eating (p-value=0.026) were significantly associated with poorer sleep quality. Conclusion: This study underscored the high prevalence of poor sleep quality among adults living in Terengganu, Malaysia. The findings could serve as a basis for developing sleep education strategies that are tailored to improve sleep quality among adults.

Burkholderia cepacia complex (Bcc) is an emerging nosocomial pathogen, with violet-pigmented strains representing a rare and possibly neglected but clinically important subset. We report a case of a 62-year-old man with end-stage renal disease on dialysis who presented with fever and cough. Blood cultures from central and peripheral lines grew violet-pigmented, non-lactose fermenting colonies on MacConkey agar, later identified as Burkholderia contaminans sequence type 922 (ST922) via a multimodal approach. Initial phenotypic methods (VITEK-2, API20NE and MALDI-ToF) and 16S rDNA sequencing were inconclusive; however, multilocus sequence typing confirmed ST922, a strain previously reported in India and associated with nosocomial outbreaks. The isolate was susceptible to ceftazidime, trimethoprim/sulfamethoxazole, minocycline, and meropenem. The patient responded well to intravenous ceftazidime, with subsequent blood cultures yielding no growth. Notably, antimicrobial susceptibility varied geographically, with some ST922 isolates resistant to third-generation cephalosporins. This case illustrates the diagnostic challenges in Bcc speciation and highlights the value of molecular tools such as MLST. The detection of this strain in Malaysia raises concerns about global dissemination, potentially via contaminated medical devices or water systems. Early recognition of violet-pigmented Bcc in resource-limited settings can facilitate prompt, targeted treatment. This report underscores the need for environmental surveillance and antimicrobial stewardship to prevent spread, while reinforcing Bcc’s ecological adaptability and clinical significance, especially in immunocompromised individuals.

Introduction: Early identification of patients at risk for severe multisystem inflammatory syndrome in children (MIS-C) is essential for favourable clinical outcomes. This study aims to identify the clinical characteristics, factors and outcomes associated with severe MIS-C. Materials and methods: In this retrospective cohort study involving 14 major hospitals in Malaysia, children <15 years who met the United States Centres for Disease Control and Prevention case definition for MIS-C were included. Severe MIS-C was defined as children who required inotropic support, ventilatory support (invasive or non-invasive ventilation), or left ventricular ejection fraction of <55%. The factors investigated for severe MIS-C were demographic characteristics, the presence of comorbidities, clinical characteristics, and laboratory measures. Multivariable logistic regression was used to compute the adjusted odds ratio (aORs) of factors associated with severe MIS-C. Results: Among the 155 patients, 91 (58.7%) presented with severe MIS-C. Severe MIS-C was more likely in patients aged ≥5 years old (aOR 2.13, 95% confidence interval [CI] 1.08-4.21), with dehydration (aOR 3.80, 95% CI 1.53-9.45), lethargy (aOR 2.02, 95% CI 0.97-4.18), tachycardia (aOR 8.33, 95% CI 3.27-21.22), albumin <30g/L (aOR 3.36, 95% CI 1.58-7.13), creatine kinase >200U/L (aOR 3.68, 95% CI 1.57-8.64), D-dimer >3.0µg/mL (aOR 2.11, 95% CI 1.08-4.13), ferritin >500ng/mL (aOR 3.77, 95% CI 1.88-7.55), prothrombin time >12.7 seconds (aOR 3.22, 95% CI 1.61-6.43), and urea >6mmol/L (aOR 5.09, 95% CI 2.04-12.71). Conclusion: Identification of these associated factors of severity in MIS-C could aid in early recognition and prompt escalation of care, leading to better outcomes.

Methods: In total, 185 lesions were identified on bone and SPECT-CT scans from 32 patients. Lesions were classified as metastatic (109 sclerotic lesions) and benign (76 lesions) morphologically on low-dose CT. Semiquantitative analysis using SUVmax and mean HU was performed on the lesions and compared. To discriminate benign and metastatic lesions, the correlation between SUVmax and mean HU was determined using the intraclass correlation coefficients. Results: The SUVmax was higher in metastatic lesions (20.66±14.36) but lower in benign lesions (10.18±12.79) (p<0.001). The mean HU was lower in metastatic lesions (166.62±202.02) but higher in benign lesions (517.65±192.8) (p<0.001). A weak negative correlation was found between the SUVmax and the mean HU for benign lesions, and a weak positive correlation was noted between the SUVmax and the mean HU on malignant lesions with no statistical significance (p=0.394 and 0.312, respectively). The cutoff values obtained were 10.8 for SUVmax (82.6% sensitivity and 84.2% specificity) and 240.86 for the mean HU (98.7% sensitivity and 88.1% specificity) in differentiating benign from malignant bone lesions. Conclusions Semiquantitative assessment using SUVmax and HU can complement qualitative analysis. Metastatic lesions had higher SUVmax but lower mean HU than benign lesions, whereas benign lesions demonstrated higher mean HU but lower SUVmax. A weak correlation was found between the SUVmax and the mean HU on malignant and benign lesions. Cutoff values of 10.8 for the SUVmax and 240.86 for the mean HU may differentiate bone metastases from benign lesions.

The present study aimed at exploring whether sunlight exposure might account for the relative difference in COVID-19-related morbidity and mortality between tropical and non-tropical countries. A retrospective observational study was designed and data from the World Health Organization weekly COVID-19 epidemiological update was compiled. We examined the total number of confirmed COVID-19 cases per 100 000 population, as well as the total number of COVID-19-related mortalities per 100 000 population. Solar variables data were obtained from the Global Solar Atlas website (https://globalsolaratlas.info/). These data were analyzed to determine the association of sunlight exposure to COVID-19-related morbidity and mortality in tropical and non-tropical countries. Results revealed a statistically significant decrease in the number of confirmed COVID-19 cases per 100 000 population (P<0.001), as well as the number of COVID-19-related mortalities per 100 000 population (P<0.001) between tropical and non-tropical countries. Analyses of sunlight exposure data found that specific photovoltaic power output, global horizontal irradiation, diffuse horizontal irradiation and global tilted irradiation at optimum angle were significantly inversely correlated to COVID-19-related morbidity and mortality. This suggests that stronger sunlight exposure potentially leads to lower COVID-19-related morbidity and mortality. Findings from this study suggest that the relatively low COVID-19-related morbidity and mortality in tropical countries were possibly due to better sunlight exposure that translates into adequate vitamin D status.

The increasing number of homeless children is concerning. This study aimed to assess the dietary intake, diet quality, and nutritional status of homeless children in Klang Valley, as well as the relationship between diet quality and nutritional status. Methods: Approximately 120 homeless children aged 7 to 12 years from four locations in Klang Valley were enrolled. Their dietary intake and nutritional status were assessed using a two-day 24-hour dietary recall and body mass index-for-age, respectively. The Healthy Eating Index (HEI) was used to examine diet quality. Results: Prevalence of normal weight respondents was 58.3% (mean±SD: -0.79±1.80), with 25.0% classified as moderately and severely thin. Mean energy intake was significantly lower than recommended nutrient intakes (RNI) (p<0.050), while protein intake was higher (p<0.050). Calcium and zinc intakes were also significantly lower (p<0.001). Boys aged 7-9 years had significantly higher iron intake (median=11.6, IQR=8.7 mg, p=0.003), whereas girls aged 10-12 years had significantly lower intakes of iron (mean±SD=11.4±5.1, 11.1±4.7) and vitamin A (median=416.6, IQR=450.4 µgRE, p<0.001 for both). Mean HEI score was 51.30±6.78, indicating a need for diet quality improvement. No significant association between diet quality and nutritional status was observed (p=0.380). Conclusion: This study provided insights into dietary intake, diet quality, and nutritional status of homeless children. Further research is vital to shape evidence-based nutrition interventions.

“Fake braces” is a term used to describe fixed orthodontic appliances that are fitted by unlicensed providers. This trend has raised public health concerns in certain countries with marketing typically undertaken on social media. We aimed to investigate the frequency and nature of Instagram posts by fake braces providers in Malaysia. Initial screening of Instagram accounts was performed using relevant hashtags (#fakebraces, #cheapbraces). Public Instagram accounts that fulfilled the inclusion criteria were assigned a code with posts evaluated over a one-month period. Data were coded and analysed using thematic analysis. Frequency distribution was calculated using Microsoft Excel. Thirty-eight Instagram accounts were analysed. 2831 images/videos were posted, receiving 7165 likes with videos being viewed 21, 918 times. The majority of posts were related to fake braces services (36.7%), followed by non-relevant posts (29.4%) and other services (14.5%). Services were provided mainly at home (44.7%) or offered both home and door-to-door services (23.7%). Although the posts on promotions were less frequent (5.4%), the displayed prices were low (RM150 to RM500), offering additional packages and discounts. Unlicensed providers have a variety of content to engage with social media audiences. Efforts should be made to increase public awareness, directing them towards reliable information about orthodontic services.

Background: Most undergraduate dental students were concerned regarding the transmission of the COVID-19 virus through their profession. This dread and anxiety may be attributable to a lack of comprehension regarding the necessary precautions and protocols to implement to ensure safety and limit potential infection threat. This study aims to assess COVID-19-related knowledge, attitudes, and practices (KAP) among undergraduate dental students at the Faculty of Dentistry, Universiti Malaya. Methods: A cross-sectional study design was used, involving 166 respondents who were undergraduate dental students from years II to IV. Data collection was achieved using a pre-tested web-based questionnaire. Descriptive and inferential analyses, including independent t-tests and one-way analysis of variance (ANOVA) tests, evaluated the KAP differences related to demographic factors. Results: There were no statistically significant differences in mean KAP associated with demographic factors such as gender, place of residence, and year of study (p > 0.05). Conclusions Dental students at the Faculty of Dentistry, Universiti Malaya, Malaysia, had adequate knowledge of COVID-19 in light of the country’s quarantine status and pandemic context.

Introduction: In Malaysia, the adolescent health studies conducted in 2012 and 2017 revealed an increasing trend of adolescent health risk behaviours and protective factors. This current study aims to determine health risk behaviours and protective factors among adolescents in the country. Methods: The current nationwide cross-sectional study of Malaysian secondary school students used multistage stratified sampling to select 240 nationally representative schools. This study was conducted from June to July 2022 among the students in forms 1, 2, 3, 4, and 5 in all Malaysian states by 34 data collection teams. A validated self-administered questionnaire was used, similar to those used in the NHMS 2012 and NHMS 2017. The quality control was done twice, once at the field level and once at the central level. Sample weighting and analysis were conducted using SPSS statistical software version 28.0. Results: A total of 239 schools out of 240 schools took part in the study (response rate, 99.6%) and total of 33,523 students were involved in this study (response rate, 89.4%). In terms of ethnicity, the highest number of students who participated in the study were Malay (63.0%), followed by Chinese (18.1%) and Indian (6.0 %). While the distribution of sex and form among the students were almost the same. Conclusion To obtain an accurate representation of the nation's adolescent population for this study, samples from public and private schools that are governed by the Ministries of Education and Rural and Regional Development were deemed to be the most reliable.

Purpura fulminans (PF) is a severe clinical manifestation of Neisseria meningitides infection that is associated with high mortality rates in children. Survivors are frequently left with debilitating musculoskeletal sequelae. There is a paucity of reports on the musculoskeletal pathology of purpura fulminans. We report on a 2-year-old boy with purpura fulminans due to meningococcemia. The child developed distal gangrene in both the upper and lower limbs. Amputations were done for both lower limbs. Histological examination of the amputated specimens showed an inflammatory process and features of osteonecrosis. The latest follow-up at the age of 6 years showed a right knee valgus due to asymmetrical growth arrest of the proximal tibia. PF and its complications are challenging to treat and may require a multidisciplinary approach to improve patient’s functional ability.
